If you compile with -version=TraceAllExceptions all
Exceptions(object.Exception and derived classes) will be traced.
sample:
# import cn.kuehne.flectioned;
# import std.utf, std.stdio;
#
# void main(){
# try{
# toUTF16("a\xFFb"c);
# }catch(Exception e){
# writefln("(%s) %s", e.classinfo.name, e);
# foreach(step; TracedException.retraced[e]){
# writefln("%s", step);
# }
# }
# }
dmd -version=TraceAllExceptions sample.d && ./sample
# (std.utf.UtfException) 4invalid UTF-8 sequence
# 0xFFCA5438 0x8061716 dchar std.utf.decode(char[], uint*)
# 0xFFCA546C 0x8061E09 wchar[] std.utf.toUTF16(char[])
# 0xFFCA54A8 0x804ADF6 int main(char[][])
# 0xFFCA54D8 0x80513AF extern(C) int main(int, char**)

Good work Mr. Kuehne! I would like to see this in phobos (I hope Mr. Bright is reading this thread :)

It sure would be nice to have a stack trace printed by default. Most of the time I fire up windbg with D, it's to trace an Access Violation. This would make debugging D apps ten times faster. And much less painful. Why not incorporate that backtrace patch someone posted into Phobos?

Shinh's only works on win32 , its still very useful , but this code works on linux + win32. I'd really love to see this for tango also. Charlie torhu wrote:Dejan Lekic wrote:Good work Mr. Kuehne! I would like to see this in phobos (I hope Mr. Bright is reading this thread :)

We are planning to add this in the 0.96 timeframe, but are dependant on Thomas porting it to Tango for us :) -- Lars Ivar Igesund blog at http://larsivi.net DSource & #D: larsivi Dancing the Tango

Because nothing that anyone writes for Phobos ever seems to make it in. :\ (A notable exception would be std.cpuid.)

Well... I did manage to get a change to the GC incorporated (setting array.length = 0 no longer invalidates the allocated RAM), so keep on lobbying <G>. -- Derek (skype: derek.j.parnell) Melbourne, Australia "Justice for David Hicks!" 8/02/2007 11:39:33 AM

Yes++. SOME kind of built-in core dump/stack trace ability in dmd would make debugging sessions go *much* faster than the current binary search for the offending line with writeflns. --bb

sarcasm { But Bill! Isn't it just so easy to load your program into the debugger and have it break on segfault? } I especially love tracking down really insidious segfaults which are data-dependent or which don't rear their head until half an hour into execution. Yeah, it's completely practical to load the program into the debugger then. I put shinichiro's stacktrace patch into Phobos a few months ago and LOVED it. Of course it went away when I updated DMD, and I never got around to putting it back in, but..
